Polar bears are increasingly suffering from the effects of climate change, including starvation, longer fasting periods, and conflict with humans.
Polar bears experiencing longer fasting periods due to sea ice loss suffer from malnutrition and physiological stress. Cubs born to malnourished mothers have lower survival rates. Bears venturing into human settlements face lethal control. As their range shrinks, territorial competition increases. The psychological experience of persistent hunger in an intelligent animal constitutes significant suffering.
